Please review my plan for re-do near boiler piping

Hi - thanks for all the help so far.  I now have the boiler water level stabilized with the help of the VXT.  Now I'm on to fixing the near boiler piping.  I believe that this is causing the water to leave the boiler to quickly.

Below are model's of what I plan on doing with the near boiler piping (The header is 3 inch, risers are 2 1/2 inch, equalizer is 2 inch).

Questions for the Pro's:

- Any problems that you can see with my plan?

- Is it ok to have a 90 degree turn on the header?

- Do I have the proper swing joints?

Any comments/suggestions would be greatly appreciated.  I'm thankful to have the resource - I can do the work myself if I have the proper information to get it done - I have not had any luck finding that resource locally.

    Looks OK so far

    I've elbowed headers like that when needed.

    Refresh our memory, what make and model boiler do you have?

    I think I saw an elbowed header once or twice.

    Oh yeah the picture I have here. I have not had any issues with elbows as long as all the other piping rules are followed. Make sure that elbow does not become a collection spot for condensate.

    like this?

    Replace one of the elbows leaving the boiler with a horizontal tee so you can skim. You might already have this, couldn't tell. I piped my boiler like your plan. The risers are off-vertical so the header slopes to the equalizer. Looks kinds kinda ghetto but doesn't hurt functionality.

    boiler type

    Sorry, the boiler is a Dunkirk PVSB 6D.
  • Boiler Piping.

    Looks good! The only suggestion that I would make is that you might want  to switch the tee around at the bottom of the Hartford Loop so you get a straight shot into the boiler thru the tee.  I use a hex reducer bushing and a boiler drain there. `If you want a thorough cleaning you can then remove the bushing and do a full port flushing. If you use an anti seize compound on the threads, the bushing /drain unit comes off easily.

    Header 3

    Went over the our building today to check out the plan for re-doing the near piping. 


    Is it ok for my riser out of the header to be 2 1/2 inch pipe, then into a 5" pipe, and then back into a 4" pipe?  Will this cause problems?  Or would this be a good thing?  The reason that I ask is that is how it is setup now.  If it would work just the same, then I'd just connect my riser out of the header into the existing piping at the ceiling.  If not, then I'll also redo that.

    I will seperate the mains - 2 risers out of the header and 2 seperate mains (1 to the right and 1 to the left).

    Basically, I'd like to seperate the returns - then just connect into that 2 1/2 pipe coming from the existing header - would this be ok?

    Thank You.

    Google Sketch

    I used Google Sketch to make the models - awesome FREE software.

    I concur...looks great (the image..not qualified to comment on the actual piping!)....but I've never had a chance to use Sketchup for plumbing. Are you drawing the pipes and fittings yourself or are you finding them as online components somewhere?

    Google Sketchup

    re: online components somewhere?

    Yes, you can just download the components within Sketchup - I just did a few searches and found that the had all the different components in the different sizes - i.e. - 2 1/2 inch 90 elbow, 3 inch tee, etc.  It'll help me visualize and order what I need.
